IMPLEMENT-ADJUSTING MEANS.

Application sied January 23, 1923. serial No. 614,441.

j To all whom @'15 may concern.'

Be it known that I, RILEY MCCLASKEY, a citizen of the United States, residing at Idaho Falls, in the county of Bonneville and State of Idaho, have invented a new and useful Implement-Adjusting Means, otl which the following is a specification.

This invention aims to `provide a com bined weeder and lister which will be of easy draft, wide latitude of adjustment being provided, novel means being supplied for varying the position of the cutting blades, and novel means being supplied for raising and lowering the plow share. with respect tothe soil..

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains. i

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the Vdetails of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, a device constructed in accordance with the invention; Figure 2 is a. side elevation; Figure 3 is a longitudinal section, most parts appearing in elevation, and parts being broken away; Figure 4 is a section on the line 4-4 of Figure 3.

In carrying out the invention, there is provided a loop-shaped wheel-mounted main frame 1 having a reduced rear eXtension 2 whereon a standard 3 is mounted, the standard carrying a seat 4. The frame 1 has a reduced forward extension 5 provided with suitable means 6 for supporting a draft tree 7, the extension 5 carrying a beau ing 8 wherein the stem of a rearwardly extended fork 9 is journaled, a ground wheel 53 being journaled on the fork 9. To the upper end of the stem of the fork 9, a tongue 10 is secured.

Bearings 11 are mounted on the side portions of the frame 1 and receive the intermediate portion of an arched axle 12 hav`V ing depending arms 14 provided with outstanding spindles 15, on which ground wheels 16 are journaled, the spindles 15 be;

ing of sutlicient length to provide for the necessary inward and outward adjustment of the ground wheels 16. Adjacent to its forward end, the side portions of the frame 1 are connected by braces 17 having depending ends 18, braces 20 extending between the ends 18 of the members 17 and the side portions of the frame 1. Radius rods 19 eX- tend between the side portions of the frame 1 and the axle spindles 15.

A clevis 21 is mounted for vertical adjustment on the depending ends 18 of the braces 17, the beam 22 of a plow share 23` being connected at its forward end to the clevis 21.

Bearings 24 and 30 are loca-ted beneath the plow beam 22, the bearing 30 being disposed to the rear of the bearing 24. A segment 28 is located above the plow beam 22 and has feet 29 connected by securing elements 25 with the bearings24 and 30. In the bearing 24 a shaft 26 is journaled, the shaft having squared ends 27. The forward foot of the segment 28 is straddled by the forks 31 of a lever 32, the forks being i mounted on the squared ends 27 of the shaft 26. The lever 32 is supplied with a latch mechanism 33 adapted to cooperate with the segment 28. Forwardly extended clamps 34 are held at 35 on the squared ends 27 of the shaft 26 for adjustment longitudinally of the shaft. Depending standards 36 are held at 37, for vertical adjustment in the forward ends of the clamps 34, the clamps constituting, in effect, crank arms on the shaft 26. Soil-engaging elements, such as weeding blades 38 are mounted on the lower ends of the standards 36 and since the standards 36 may be adjusted vertically in the clamps 34, the blades 38 may be adjusted vertically with respect to the soil.

Upstanding bearing posts 39 are erected on the side portions of the frame 1 to the rear of the hanger 17-18 and are sustained from the frame by braces 40. A lirst shaft 41 is mounted to rock in the bearing posts 39 and has a squared intermediate portion 42 retaining rearwardly extended arms 43 whereunto downwardly extended links 44 are pivoted, the links 44 being disposed at an a-cute angle to the vertical, and lower ends of the links being connected to a shaft 45 mounted to rock in the bearing 30 on the plow beam 22. The shaft 41 carries a depending arm 46, located at one end of the Shaft.' i u The forward end of a first link 47 tloeated about the frame is pivoted tothe arm'46 andthe 'rear end of the link is pivtedto a first lever 48 fulcrumed intermediate its ends on one side portion ofthe frame land pro vided with a latch mechanism 49 adapted to coact with a segment 50 on the frame A1; A retractile spring 5l is secured at its lower end to the lever 48, below the fulc'r'uin ofthe lever, the. forward end of the spring 5.1 being adjustably secured at '52 to one side portion of the frame l, as shown best in Figure 1'.

Through the instrumentality of the lever 48, the link V47, the arm 46, the shaft v41,the

arms 43 and the 'secondlinks 44, the beam 22 and the plow share 23 may be raised and lowered with the connection between the clevis 21 and tlie parts 18 "as a ulciiim. Rotation may be imparted tothe second shaft 2G by way of the :second lever 32, theg'forward ends of clamps for crank arms l34 swinging pwardly and downwardly, 'the angle between the blades I38 andthe Siirface of the soil being varied, and the pcsition of the blades with respect to the share 23 being adjusted; Since the standards `86 which carry ther blades 38 may befadjuste'd vertically in theclamps B4, the blades 38 maybe raised and lowered for adjustment, with 'respect to the soil. i

lVhat is claimed is In a device yof the class described, a wheelmounted frame, a depending hanger carried by the frame, ka beam located below the rst lever and "to the depending arm of the first shaft, a 'second link disposed between the shaft and the 'first lever Afand disposed at 'an aeute afiiglefto the vertical, thel second link being pijvoted`-to the refarwardl` entended arm f the iirst sha-ft, and to.` the Y be'ai'n near te the rear-thereof, a secbnd `shaft inonnted to rock on the beam, a foi'Wa-rdlj' extended arm carried 'second shaft, a

dswewardi'yexfdieg Sti-1 @mgm-hg el- -met mounted@ the last-speciaal: arm, an upstahding second lever mointed' on` the secnd shahe latch mechanism ared the second lever, and a segment on the bleef-n', the latch mechanism Lc'lpeiat'i'g with; the segment. e i A,

In testimenv tht'I 'foregoing as'my own, I have hert tiire iii the presence of twb "vifitnesses,`
